How Cirencester compares
Small towns rarely get published solar figures, so here are the numbers for Cirencester. It is one of 24 Gloucestershire towns we track, and it ranks joint 8th of 24 for solar yield, a town of 17,967 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,009 kWh per kWp a year, 2.76 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £905 of year one benefit, £247 of it from your own generation and £658 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Cirencester's own yield, and prices a 12 panel system at £6,360 installed before any battery. Your free design call reworks every number for your actual roof, its shading and your usage.
Planning applications here go through Cotswold; nationally, the House of Commons Library classes Cirencester as a small town.
The charger is in the installed price but left out of payback: charging savings depend on your mileage and tariff, which the design call models properly.

Generation is modelled from PVGIS satellite data for Cirencester's own coordinates (51.71177, -1.96651), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
SSEN and your Cirencester connection
Cirencester sits in Scottish and Southern Electricity Networks' Southern England licence area, so SSEN is the network operator (DNO) any solar panels or battery here are registered with.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, SSEN only has to be told within 28 days after the system is commissioned.
Larger systems go through G99 instead, applied for before installation. On timing: SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW.

Heat pumps and EV charging in Cirencester
A heat pump in Cirencester
In December, the darkest month here, 12 panels in Cirencester make about 220 kWh. That is when a heat pump runs hardest, so its running cost in Cirencester comes down to the tariff and the flow temperature rather than the roof.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Cirencester
Summer is where a car earns its place. In July, 12 panels in Cirencester make about 800 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Solar in Cirencester: your questions answered
How much electricity do solar panels make in Cirencester?
About 6,420 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Cirencester: 1,009 kWh per kWp, or 2.76 peak sun hours a day on average. July is the strongest month, at about 800 kWh.
What does a typical solar system cost in Cirencester?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Cirencester, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,420 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Cirencester, and what does it need from me?
Scottish and Southern Electricity Networks (SSEN) covers Cirencester. A home system of up to 3.68kW per phase is notified to SSEN within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW.
What happens to the solar I do not use in Cirencester?
Around £658 a year at 12p per kWh, for the roughly 5,481 kWh a 12-panel system in Cirencester exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Cirencester get in December?
December is the low point: about 220 kWh from a 12-panel system in Cirencester, on PVGIS data, rising to 800 kWh in July. From November to February the same system makes about 1,080 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Cirencester compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Cirencester.
| Town | kWh per kWp a year | vs Cirencester |
|---|---|---|
| Cirencester | 1,009 | this town |
| Malmesbury | 1,018 | +9 kWh |
| Stroud | 998 | −11 kWh |
| Royal Wootton Bassett | 1,018 | +9 kWh |
| Highworth | 1,018 | +9 kWh |
| Swindon | 1,018 | +9 kWh |
| Brockworth | 990 | −19 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
